Among the marine maintenance products Practical Sailor evaluated recently were 14 pump-spray mildew cleaners to find out which one was the most effective at removing severe mildew stains. We tested chlorine bleach cleaners, chlorine-free cleaners, hydrogen peroxide cleaners, and ammonium chloride cleaners on a variety of materials, ranging from mildewed shower curtains to moldy vinyl seat cushions and moldy life jackets. We also used them to clean a mildewed sail and mildewed Sunbrella. All products were effective at removing the mold mildew from the shower curtain, but the cushions, life jacket, Dacron sail, and Sunbrella were more of a challenge. One product stood out as a more effective mildew cleaner: Klean-Strip Mildew Stain Remover. Klean-Strip is a highly concentrated product with 19 times more sodium hypochlorite than common bleach, and we do not recommend it for cleaning sails or fabrics. Other products tested include 3M mildew stain remover, Boat Armor mildew stain remover, Boatlife mildew remover, MaryKate mildew stain remover, MDR Amazons Amazing Mildew Stain Away, MDR Moldaway, Naturally Clean Mildew, Nautical Ease Mildew Stain Remover, household Spray Nine, Star brite Mildew Stain Remover, Sudbury Mildew Cleaner and Stain Remover, Thetford Mildew Stain Remover, and West Marine Mold and Mildew Cleaner.
Even when your anchor is well designed and ideally matched to your boat, there are four common factors that can cause an anchor to drag: poor bottom, short scope, insufficient shock absorption, and yawing. Each of these reduces the holding capacity of the anchor, and they are additive. That is to say that any one of them can ruin your day, solving only one or two of them does not ensure good holding, and the more problems you solve, the better youll sleep.
In order to impart corrosion resistance to steel, the items are commonly galvanized, immersed in a bath of molten zinc. Hot-dip galvanizing is well established and accepted, but there are alternate technologies like sherardizing.
Testers evaluated five different knots to determine which would be the ideal for holding a tensioned line. Testers considered ease of tying and untying, ease of learning and recall, and holding power with various types of line. The old standard rolling hitch was pitted against the modified rolling hitch, icicle hitch, gripper hitch, and sailors hitch.
Testers put six rope clutches through their paces on a test jig that measured line tension, line slippage, and the clutches holding ability over a long period of time. In terms of overall value and performance, the units tested were a tightly grouped field of competitors. Practical Sailor testers evaluated rope clutches from Euromarine Trading (Antal), the Antal V-cam 814 and Antal V-grip Plus; Lewmar D-1 and Lewmar D-2; Spinlock XCS and Spinlock XTS; and a prototype clutch from California-based Garhauer Marine Hardware. The search for the best rope clutch took a look at the pros and cons of employing a rope clutch for specific tasks as knowing when to clutch and when not to clutch is imperative for efficient line handling and safety.
